To @ZZ whom, t may concern/.-

Be it known that' I, FORD ADDISON MAN- SELL, merchant, a subject of the King of Great Britain, residing in 'the town of .Tren-v ton, in the county of Hastings, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Window-Screens, of which the following is a speciiication.

My invention relates to improvements in window-screens; and the Object of my invention is, first, to design a screen that Vcan be used in connection with allkinds of windows; secondly, to design a screen that can be attached to the Window-sash and permit same to be raised up and'down without necessitating the removal of the window-.screen therefrom, and, thirdly, to design .a neat, cheap, andcompact window-screen; and it consists, broadly, in combining with a window-frame and sash for same a Window-screen comprising a spring-controlled roller, two brackets in which said roller is journaled, a suitable netting wound around said roller, two plates secured at their inner ends to said brackets and above said roller and netting thereon, their inner edges being wide enough apart to permit the netting to pass therebetween, and means secu red to the freel end of said netting by means of which the netting is secured to' the under side of a Window-sash. In carrying out my invention I form a suit able chamber in the window-sill immediately below the window-sash and place my windowscreen therein. K construction, that Will be hereinafter more particularly explained.

Figure lis a general perspective of my win-4 3 is a section on the line e f, Fig. 2, looking in the direction indicated by arrow. Fig. 4 is a Vertical section on the lines c d, Fig. l, looking in the direction indicated by arrow. Fig. 5 is a vertical section through one end of the spring-controlled roller. Fig. 6 is a There are other details of.

- plan view of a suitable'device used for locking the window-screen to the Window-sash. Fig. 7 is a cross-section through the yhead of the window-screen, showing one means by which the netting may be secured thereto.

In' the drawings like letters of reference in` dicate corresponding parts iu each figure. A is any suitable roller mounted at one end in vthe bracket B by a spindle C and mounted at its other endin the bracketD by the spine dle E. I preferably use a hollow roller for manufacturing my Window screen. Cone tained within the roller Aand at one end of same is a suitable spring F, whichV is secured at one endf to said roller and is secured at the other end at o; to a disk o, which is suitably keyed tothe spindle C. h is a cap inclosing this end of the roller.

Keyed to the spindle C at the outer side of the bracket B is a pinion G, which meshes with a ratchet-wheel H, keyed to a stud I, suitably journaled in the bracket B and in the casing J, which incloses these parts.` The said casing is suitably secured to the outside of the bracket B. The spindle C also has bearing in said casing.4 .The inner end il of the stud I is suitahlyiormed so that a key may operate therewith for the purpose of regulating the tension yof the spring F, as will be understood. The tendency of the spring F is of course to rotate the roller A.

Suitably pivoted to the bracket B is a pawl L, which engages with the ratchet-wheel H to prevent movement of same in one direc tion. I essentially use a spring in connection with my roller and use suitable means forpreventing said spring from being unduly unwound, ,and although I have minut-ely described the parts for this purpose l do not confine myself to same, as many different devices could be designed for this purpose Without departing from the spirit of my invention.

Fitting within the opposite end of the roller A is any suitable thimble M, provided with a cap N. Heldin the inner end m of said thimble and said cap N is the spindle E. Suitably secured to this spindle is aspring O. It will be understood that as soon as the roller is placed in position the spring 0 will force the spindle E into its bearing in the bracket D.

ois any suitablel disk secured within the thimble M for giving additional bearing to IOO the spindle E. ,I preferably use a springcontrolled spindle at this end of the roller for the purpose before described, but do not confine myself to the construction herein shown and described. It will be noticed that the cap N has the same external diameter as the roller A, thus providing an even surface for the netting to be wound around.

P is the window-sill, which is hollowed out directly beneath the sash, asshown at Q.

R represents the usual guides between which the sash S operates.

T is any suitable netting wound around the roller A. At the outer end ot' this netting is secured a plate U, which is ofthe same width and length as the sash S. It will of course be understood that the roller A and its netting are also of the same width as the sash.

In the construction shown in the drawings the plate Uis provided with two downwardlyprojecting ribs V and V', between which the said netting is held in any suitable manner. I incluse the roller A and its netting Within the space Q as much as possible by means of two suitably-shaped plates t; and u, which are suitably secured in place to the windowsill and also to the brackets D and B. Between the inner edges of these plates it will be noticed that there is a space tu, in which operates the netting. When the sash S is lowered to its lowest point, it forces the plate U down upon the plates o and tt, vthus passing the ribs V and V into the space fw. It

wllbe noticed that the outer plate@ is curved downwardly to correspond with the lower shape ot' the window-sash. This construction prevents any Waterfrom getting down ontov the'netting. In case the plate o is a particularly long one I-support same at its under side by any suitable brackets W, suitably secured to the window-sill.

In order to detachably secure the suitable .plate U to the bottom of the window-sash, I

'I employ the following construction: I drillv a hole up through the plate U and insert therein the stud 3. I piercethe ribsV and Vl with a hole 4 for the purpose of enabling me to placev the stud 3 in place. Suitably secured to the upper end of the stud 3 is a head 5. Cou ntersun k in the under side of the sash S is anysuitable plate 6, provided with a slot 7. When it is desired to lock the screen to the sash S, the head 5 of the stud 3 is passed through the slot 7 and turned sidewise, as shown in Fig. 3, thus engaging with the plate 6. The sash 7 is recessed, as shown at 8, in order to permit of the movement of the head 5. I move the stud 3 by means of any suitable pin 9, secured thereto, which operates in a slot 10, formed in the rib V. Although I have described minutely this means for securing the screen to the sash, I do notcontine myself to same, as different devices could be designed for this purpose without departing from the spirit of my invention.

As the roller A is always operated by the spring F to wind up the netting, it will be understood that the same will always be held taut. A great advantage derived from using my screen is that no matter in what position the window-sash may be in the screen is always in position for use. When once my window-screen is placed in position, it is intended that same shall not ordinarily1 be unlocked from the sash. As the sash can be raised up and down freely, it will be seen that it will not be necessary to unlock the screen therefrom.

It will be understood from the specification and claims that I may dispense altogether with the use of the plates o and u in connection with the other elements of my windowscreen without departing from the spirit of my invention.
